[0218] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0219] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0220] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0221] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0222] To support direct communication between terminals, a direct link (also called sidelink, SL) communication mode is introduced. The interface between terminals is PC-5 (also called PC5). Three transmission modes are supported on the sidelink: unicast, multicast, and broadcast, depending on the correspondence between the transmitting and receiving terminals. The transmitting terminal sends sidelink control information (SCI) on the physical sidelink control channel (PSCCH) and second-stage SCI on the physical sidelink shared channel (PSSCH). These SCIs carry information such as the resource location of the transmitted data and the source and destination identifiers. For packets with Hybrid Automatic Repeat Request (HARQ) feedback enabled, the receiving terminal sends a Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) on the physical sidelink feedback channel (PSFCH).

[0223] In some embodiments, sidelink communication has two modes of allocating transmission resources: one is the network's dynamic scheduling mode (mode 1, also called the first resource allocation mode), and the other is the terminal's autonomous selection from a network-configured or pre-configured resource pool (mode 2, also called the second resource allocation mode). Dynamic scheduling means the network dynamically allocates transmission resources on the sidelink to the terminal based on the terminal's cached data report, while autonomous selection means the terminal randomly selects transmission resources from a network-configured or pre-configured resource pool. The network can configure multiple resource pools for a terminal on a BWP (Bandwidth Part). The specific allocation mode used is configured by the network side through RRC (Radio Resource Control) signaling.

[0224] Carrier aggregation is a key technology in LTE-A. To meet the requirements for single-user peak data rates and improved system capacity, one of the most direct approaches is to increase the system transmission bandwidth. Therefore, LTE-Advanced introduces a bandwidth-enhancing technology called Carrier Aggregation (CA). CA aggregates multiple carriers (also called component carriers, CCs) to effectively increase uplink and downlink transmission rates.

[0225] LTE V2X supports sidelink carrier aggregation technology. Due to limited transmit and receive capabilities, terminals may only be able to receive sidelink services on one or several carriers. LTE V2X does not introduce any carrier selection / reselection enhancements to address the limited receiving capabilities of terminals. The reason is that LTE V2X only supports broadcast services and can rely on higher-layer implementations to determine which services are of interest and receive data only on carriers associated with the services of interest.

[0226] In some embodiments, in the NR Sidelink carrier aggregation scenario, the Inter-UE coordination (IUC, terminal internal coordination) mechanism can be supported, so as to assist the opposite UE to better select resources and avoid conflicts with other UEs. Exemplarily, a first terminal in mode 2 (such as UE-A) can send a SLIUC MAC CE to a second terminal in mode 2 (such as the opposite UE-B), which can carry a preferred resource set (preferred resource set) or a non-preferred resource set (non-preferred resource set), so that the opposite UE-B can provide assistance when selecting resources. If the SLIUC MAC CE carries the preferred resource set, UE-B can only use the preferred resource set to send data to UE-A and cannot use it to send data to other UEs. If the SLIUC MAC CE carries the non-preferred resource set, UE-B cannot use the resources indicated by the non-preferred resource set when sending data to UE-A.

[0227] In some embodiments, SL IUC has two triggering modes: a request-based IUC mechanism and a condition-based IUC mechanism. In the request-based IUC mechanism, a first terminal (e.g., UE-A) triggers the sending of a SL IUC MAC CE only after receiving a SL IUC request (SL IUC-request) from a second terminal (e.g., UE-B) via PC-5. That is, the first terminal (e.g., UE-A) triggers the sending of a SL IUC MAC CE to the second terminal only after receiving the SL IUC request from the second terminal (e.g., UE-B) via PC-5. In the condition-based IUC mechanism, the first terminal (e.g., UE-A) determines whether a triggering condition is met. If the triggering condition is met, the first terminal (e.g., UE-A) can automatically trigger the sending of an IUC MAC CE based on implementation selection. That is, if the triggering condition is met, the first terminal (e.g., UE-A) can trigger the sending of a SL IUC MAC CE to the second terminal based on implementation selection. The request-based IUC mechanism can configure a latency bound to limit the peer UE to send SLIUC MAC CEs within the latency bound. Latency bounds do not apply to conditional-triggered IUC mechanisms. A UE (e.g., a second terminal) can configure a latency bound for a peer UE (e.g., a first terminal) via PC5-RRC (also called PC5RRC) signaling.

[0228] However, in the New Radio Sidelink (NR Sidelink) carrier aggregation scenario, how to trigger the reporting of the Sidelink Intra-Terminal Collaboration (SL IUC) report is an issue that needs to be solved urgently.

[0229] To this end, the embodiments of the present disclosure provide an information processing method and a device thereof, which can effectively improve the transmission rate of the sidelink by adopting carrier aggregation technology on the new radio interface sidelink; in addition, the first terminal sends IUC information to the second terminal based on the aggregated carrier associated with the unicast connection, so as to provide assistance to the second terminal when selecting resources, thereby providing a guarantee for reliable and high-speed communication, and can solve the problem of how to trigger the reporting of the SL IUC report in the new radio interface sidelink NR Sidelink carrier aggregation scenario.

[0230] FIG2A is an interactive diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in FIG2A , the information processing method according to an embodiment of the present disclosure can be applied to a communication system 100 , and the method includes but is not limited to the following steps.

[0231] Step S2101: The first terminal 101 receives first information sent by the second terminal 102 on a first carrier, where the first information is used to trigger the first terminal 101 to send SL IUC information of the first carrier.

[0232] In some embodiments, the second terminal 102 sends first information to the first terminal 101, where the first information is sent by the second terminal 102 on the first carrier. Accordingly, the first terminal 101 receives the first information sent by the second terminal 102 on the first carrier, where the first information is used to trigger the first terminal 101 to send SL IUC information of the first carrier.

[0233] In some embodiments, a unicast connection is established on the sidelink between the first terminal 101 and the second terminal 102, and the unicast connection is associated with one or more aggregated carriers.

[0234] In some embodiments, the first carrier is one or more carriers among the one or more aggregated carriers. Exemplarily, the first carrier can be understood as one or more carriers among the one or more aggregated carriers that are triggered to report SL IUC. Exemplarily, the first information sent by the second terminal 102 on the first carrier is used to trigger the first terminal 101 to send SL IUC information of the first carrier. Exemplarily, triggering the first terminal 101 to send SL IUC information of the first carrier can also be referred to as requesting the first terminal 101 to send SL IUC information of the first carrier.

[0235] In some embodiments, the first information sent by the second terminal 102 on the first carrier may carry carrier indication information of the first carrier. Exemplarily, the carrier indication information of the first carrier may be an index of the first carrier.

[0236] In some embodiments, the first information sent by the second terminal 102 on the first carrier may not carry carrier indication information of the first carrier.

[0237] In some embodiments, the first information sent by the second terminal 102 on the first carrier may be at least one of the following: sidelink control information (SL SCI); SL ​​IUC request MAC CE (also called SL-IUC request MAC CE). Exemplarily, the first information sent by the second terminal 102 on the first carrier may be SL SCI, or may be SL IUC request MAC CE.

[0238] In some embodiments, the first information sent by the second terminal 102 on the first carrier may be included in the SL SCI and / or the SL IUC request MAC CE. Exemplarily, the first information sent by the second terminal 102 on the first carrier may be included in the SL SCI. For example, the second terminal 102 sends the SL SCI to the first terminal 101 on the first carrier, and the SL SCI includes the first information. Exemplarily, the first information sent by the second terminal 102 on the first carrier may be included in the SL IUC request MAC CE. For example, the second terminal 102 sends the SL IUC request MAC CE to the first terminal 101 on the first carrier, and the SL IUC request MAC CE includes the first information.

[0239] In step S2102, the first terminal 101 sends a SL IUCMAC CE (also called SL-IUC MAC CE, SL IUC report, or sidelink channel state information media access control element) to the second terminal 102 on the first carrier based on the first information. The SL IUCMAC CE includes the SL IUC information of the first carrier.

[0240] In some embodiments, after the first terminal 101 receives the first information sent by the second terminal 102 (for example, the first information is sent by the second terminal 102 on the first carrier), the first terminal 101 sends a SL IUC MAC CE to the second terminal 102. The SL IUC MAC CE may be sent by the first terminal 101 on the first carrier to the second terminal 102. Correspondingly, the second terminal 102 may receive the SL IUC MAC CE sent by the first terminal 101 on the first carrier, where the SL IUC MAC CE includes the SL IUC information of the first carrier.

[0241] Exemplarily, since the above-mentioned first information is used to trigger the first terminal 101 to send the SL IUC information of the first carrier, the first terminal 101 sends a SL IUC MAC CE to the second terminal 102 on the first carrier. The SL IUC information included in the SL IUC MAC CE is the sidelink terminal internal collaboration information of the first carrier. That is, the first information sent by the second terminal 102 to trigger the SL IUC report is only sent on the first carrier that is triggered to report. The first terminal 101 only sends the SL IUC report of the first carrier on the first carrier, so that the SL IUC MAC CE sent by the first terminal 101 does not need to carry the carrier indication information of the first carrier, and the second terminal 102 can also know that the SL IUC report sent by the first terminal 101 is the SL IUC report of the first carrier. Exemplarily, the existing SL IUC MAC CE format can be reused, and the reserved bit does not need to indicate the carrier information.

[0242] Optionally, in some embodiments, the SL IUC MAC CE sent by the first terminal 101 to the second terminal 102 on the first carrier may carry carrier indication information of the first carrier. Exemplarily, it is necessary to define a new SL IUC MAC CE format to indicate the carrier information of the first carrier, such as the index of the first carrier, by reserving bits. Exemplarily, the SL IUC MAC CE sent by the first terminal 101 to the second terminal 102 on the first carrier may indicate the SL IUC information of the first carrier.

[0243] In some embodiments, the SL IUC information of the first carrier may carry a resource set. Exemplarily, the SL IUC information of the first carrier carries a preferred resource set or a non-preferred resource set, so that the second terminal 102 can provide assistance when selecting resources. If the SL IUC information of the first carrier carries a preferred resource set, the second terminal 102 can only use the preferred resource set to send data to the first terminal 101 on the first carrier, and cannot use it to send data to other UEs. If the SL IUC information of the first carrier carries a non-preferred resource set, the second terminal 102 cannot use the resources indicated by the non-preferred resource set when sending data to the first terminal 101 on the first carrier.

[0244] It should be noted that when the SLIUC report of the first carrier is triggered and the SLIUC report of the first carrier is reported, the LCP influence can be taken into consideration, and the SL IUC MAC CE associated with the first carrier can only be sent on the sidelink grant (SL grant) on the first carrier. In some embodiments, the sidelink grant is determined to be a sidelink grant on the first carrier and / or the target address of the sidelink grant is the second terminal 102; the sidelink grant is a new transmission sidelink resource (or can also be called a new transmission resource, an SL resource for new transmission); the SL IUC MAC CE associated with the first carrier is multiplexed into a sidelink media access control protocol data unit (SL MAC PDU), and the SL MAC PDU is sent to the second terminal 102 through the sidelink grant. The new transmission sidelink resource can refer to the SL resource for new transmission; the sidelink grant being a new transmission sidelink resource can be understood as the sidelink grant being used for new transmission.

[0245] For example, considering the impact of LCP, the SL IUC MAC CE of the first carrier can only be sent on the sidelink authorization on the first carrier. If the sidelink authorization of the LCP process is a sidelink authorization on other carriers, the SL IUC MAC CE of the first carrier is not considered in the LCP process.

[0246] In some embodiments, when the first terminal 101 determines that the first carrier triggers the SL IUC report and the SL IUC report triggered by the first carrier is not canceled, the first terminal 101 starts the SL IUC (sidelink terminal internal cooperation) timer associated with the first carrier; during the operation of the SL IUC timer associated with the first carrier, the first terminal 101 sends a SL IUC MAC CE to the second terminal 102, where the SL IUC MAC CE includes SL IUC information associated with the first carrier. Exemplarily, the SL IUC timer can be represented by the sl-IUC-ReportTimer parameter, or can be represented by other expressions, which are not specifically limited here.

[0247] That is to say, a SL IUC timer (also called SL IUC report timer) is maintained for each carrier associated with the unicast connection. Exemplarily, when the SL IUC report of the first carrier is triggered and the triggering status of the SL IUC report is not canceled (it can be understood that the first terminal 101 receives the first information from the second terminal 102 indicating that the SL IUC report of the first carrier is triggered), if the SL IUC timer associated with the first carrier is not running, the SL IUC timer associated with the first carrier is started, and during the running of the SL IUC timer associated with the first carrier, the first terminal 101 sends a SL IUC MAC CE to the second terminal 102, and the SL IUC MAC CE includes the SL IUC information associated with the first carrier.

[0248] In some embodiments, when the first terminal 101 determines that the first carrier triggers the SL IUC report and the SL IUC report triggered by the first carrier has not been canceled, the first terminal 101 starts the SL IUC timer associated with the first carrier; when the first terminal 101 determines that the SL IUC timer associated with the first carrier has expired, the first terminal 101 cancels the SL IUC report triggered by the first carrier. Exemplarily, when the SL IUC report of the first carrier is triggered and the triggering state of the SL IUC report is not canceled (it can be understood that the first terminal 101 receives the first information from the second terminal 102 indicating that the SL IUC report of the first carrier is triggered), if the SL IUC timer associated with the first carrier is not running, the SL IUC timer associated with the first carrier is started; if the SL IUC timer associated with the first carrier has expired, the SL IUC report triggered by the first carrier is canceled. For example, if the SL IUC timer associated with the first carrier has expired, the first terminal 101 does not generate a SL IUC MAC CE including the SL IUC information of the first carrier, and / or does not send the SL IUC MAC CE including the SL IUC information of the first carrier.

[0249] In some embodiments, during the operation of the SL IUC timer associated with the first carrier, the first terminal 101 determines that the first terminal 101 has new side link resources and the new side link resources may include a SL IUC MAC CE and a subheader of the SL IUC MAC CE, then instructs the multiplexing and assembly entity to generate the SL IUC MAC CE, send the SL IUC MAC CE, stop the SL IUC timer associated with the first carrier, and cancel the SL IUC report triggered by the first carrier.

[0250] That is to say, during the operation of the SL IUC timer associated with the first carrier, if the first terminal 101 has a new transmission side link resource and the new transmission side link resource may include a SL IUC MAC CE and a subheader of the SL IUC MAC CE, the multiplexing and assembly entity is instructed to generate the SL IUC MAC CE, stop the SL IUC timer associated with the first carrier, and cancel the SL IUC report triggered by the first carrier.

[0251] In some embodiments, the second terminal 102 sends the delay bound requirement of the SL IUC report to the first terminal 101 via PC5RRC signaling. Accordingly, the first terminal 101 receives the delay bound requirement of the SL IUC report sent by the second terminal 102 via PC5RRC signaling; wherein the duration of the SL IUC timer associated with the first carrier is the delay bound requirement of the SL IUC report. Exemplarily, the delay bound requirement of the SL IUC report can be configured by the second terminal 102 to the first terminal 101 via PC5RRC signaling.

[0252] In some embodiments, the delay limit requirement of the above-mentioned SL IUC report can be configured according to any of the following granularities: carrier granularity; frequency band granularity; frequency segment granularity; terminal granularity; target address granularity; address granularity. Exemplarily, the delay limit requirement of the above-mentioned SL IUC report can be configured according to carrier granularity, and the value of the SL IUC timer associated with the first carrier is the size of the delay limit requirement of the SL IUC report associated with the first carrier. Exemplarily, the delay limit requirement of the above-mentioned SL IUC report can be configured according to terminal granularity, and the value of the SL IUC timer associated with the first carrier is the size of the delay limit requirement of the SL IUC report associated with the first terminal.

[0253] In the above embodiment, the second terminal sends the first information on the first carrier that is triggered to report the SL IUC report. The first information is used to trigger the first terminal to send the SL IUC information of the first carrier, and the first terminal sends the SL IUC information of the first carrier to the second terminal on the first carrier that is triggered to report the SL IUC report. This can achieve the purpose of triggering the SL IUC report according to the carrier granularity, and can achieve the purpose of reporting the SL IUC report according to the carrier granularity, thereby solving the problem of how to trigger the reporting of the SL IUC report in the new radio interface side link NR Sidelink carrier aggregation scenario.

Exemplarily, triggering the first terminal 101 to send the SL IUC information of the first carrier can also be referred to as requesting the first terminal 101 to send the SL IUC information of the first carrier. Exemplarily, the first carrier can be understood as one or more carriers of the one or more aggregated carriers mentioned above that are triggered to report the SL IUC. Exemplarily, the first carrier can be multiple carriers, and the second terminal 102 can trigger the first terminal 101 to send the SL IUC information of multiple carriers by sending the first information on the second carrier. For example, the second terminal 102 can carry indication information of multiple carriers in the first information sent on the second carrier.

[0266] In some embodiments, the first information sent by the second terminal 102 on the second carrier carries carrier indication information of the first carrier. Exemplarily, the carrier indication information of the first carrier may be an index of the first carrier.

As shown in Figure 2C, the information processing method according to an embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0275] Step S2301: The second terminal 102 sends first information to the first terminal 101 on a first carrier, where the first information is used to trigger the first terminal 101 to send SL IUC information of the first carrier.

[0276] In some embodiments, a unicast connection is established on the sidelink between the first terminal 101 and the second terminal 102, and the unicast connection is associated with one or more aggregated carriers.

[0277] In some embodiments, the first carrier is one or more carriers among the one or more aggregated carriers. Exemplarily, the first carrier can be understood as one or more carriers among the one or more aggregated carriers for which SL IUC reporting is triggered.

[0278] The optional implementation of step S2301 can refer to the optional implementation of step S2101 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0280] In some embodiments, after the first terminal 101 receives the first information sent by the second terminal 102 (for example, the first information is sent by the second terminal 102 on the first carrier), the first terminal 101 sends a SL IUC MAC CE to the second terminal 102 according to the first information. The SL IUC MAC CE may be sent by the first terminal 101 on the third carrier to the second terminal 102. Correspondingly, the second terminal 102 may receive the SL IUC MAC CE sent by the first terminal 101 on the third carrier, where the SL IUC MAC CE includes the SL IUC information of the first carrier and / or the carrier indication information of the first carrier.

[0281] In some embodiments, the third carrier is one of the one or more aggregated carriers.

[0282] In some embodiments, the SL IUC MAC CE sent by the first terminal 101 on the third carrier may include the SL IUC information of the first carrier. In some embodiments, the SL IUC MAC CE sent by the first terminal 101 on the third carrier may include the SL IUC information of the first carrier and the carrier indication information of the first carrier (such as the index of the first carrier). Exemplarily, it is necessary to define a new SL IUC MAC CE format, and indicate the carrier information of the first carrier, such as the index of the first carrier, by reserving bits. Exemplarily, the first terminal 101 needs to define a new SL IUC MAC CE format, and indicate the carrier information of the first carrier, such as the index of the first carrier, by reserving bits. Exemplarily, the SL IUC MAC CE sent by the first terminal 101 to the second terminal 102 on the third carrier may indicate the SL IUC information of the first carrier. For example, the first information sent by the second terminal 102 to the first terminal 101 through carrier A indicates that the first terminal sends the SL IUC information of carrier A. The second terminal 102 sends the first information to the first terminal 101 through carrier B, indicating that the first terminal sends the SL IUC information of carrier B. The SL-IUC MAC CE sent by the first terminal 101 to the second terminal 102 includes the SLIUC information of carrier A and the SLIUC information of carrier B, as well as the carrier indication information of carrier A (such as the index of carrier A) and the carrier indication information of carrier B (such as the index of carrier B).

[0283] In some embodiments, when the first terminal 101 determines that the first carrier triggers the SL IUC report and the SL IUC report triggered by the first carrier is not canceled, the first terminal 101 starts the SL IUC timer associated with the first carrier; during the running of the SL IUC timer associated with the first carrier, the first terminal 101 sends a SL IUC MAC CE to the second terminal 102, and the SL IUC MAC CE includes the SL IUC information associated with the first carrier.

[0284] That is to say, a SL IUC timer (also called SL IUC report timer) is maintained for each carrier associated with the unicast connection. Exemplarily, when the SL IUC report of the first carrier is triggered and the triggering status of the SL IUC report is not canceled (it can be understood that the first terminal 101 receives the first information indication of the second terminal 102 to trigger the SL IUC report of the first carrier), if the SL IUC timer associated with the first carrier is not running, the SL IUC timer associated with the first carrier is started, and during the running of the SL IUC timer associated with the first carrier, the first terminal 101 sends a SL IUC MAC CE to the second terminal 102 on the third carrier, and the SL IUC MAC CE includes the SL IUC information of the first carrier and / or the carrier indication information of the first carrier.

[0285] In some embodiments, when the first terminal 101 determines that the first carrier triggers the SL IUC report and the SL IUC report triggered by the first carrier has not been canceled, the first terminal 101 starts the SL IUC timer associated with the first carrier; when the first terminal 101 determines that the SL IUC timer associated with the first carrier has expired, the first terminal 101 cancels the SL IUC report triggered by the first carrier. Exemplarily, when the SL IUC report of the first carrier is triggered and the triggering status of the SL IUC report is not canceled (it can be understood that the first terminal 101 receives the first information from the second terminal 102 indicating that the SL IUC report of the first carrier is triggered), if the SL IUC timer associated with the first carrier is not running, the SL IUC timer associated with the first carrier is started; if the SL IUC timer associated with the first carrier has expired, the SL IUC report triggered by the first carrier is canceled.

[0286] In some embodiments, during the operation of the SL IUC timer associated with the first carrier, the first terminal 101 determines that the first terminal has new transmission side link resources and the new transmission side link resources may include a SL IUC MAC CE and a sub-header of the SL IUC MAC CE; instructs the multiplexing and assembly entity to generate the SL IUC MAC CE; stops the SL IUC timer associated with the first carrier, and cancels the SL IUC report triggered by the first carrier.

[0287] That is to say, during the operation of the SL IUC timer associated with the first carrier, if the first terminal 101 has a new transmission side link resource and the new transmission side link resource may include a SL IUC MAC CE and a subheader of the SL IUC MAC CE, the multiplexing and assembly entity is instructed to generate the SL IUC MAC CE, stop the SL IUC timer associated with the first carrier, and cancel the SL IUC report triggered by the first carrier.

[0288] In some embodiments, the second terminal 102 sends the delay bound requirement of the SL IUC report to the first terminal 101 via PC5RRC signaling. Accordingly, the first terminal 101 receives the delay bound requirement of the SL IUC report sent by the second terminal 102 via PC5RRC signaling; wherein the duration of the SL IUC timer associated with the first carrier is the delay bound requirement of the SL IUC report. Exemplarily, the delay bound requirement of the SL IUC report can be configured by the second terminal 102 to the first terminal via PC5RRC signaling.

Accordingly, the first terminal 101 receives the first information sent by the second terminal 102 on the fourth carrier.

[0304] In some embodiments, a unicast connection is established on the sidelink between the first terminal 101 and the second terminal 102, and the unicast connection is associated with one or more aggregated carriers.

[0305] In some embodiments, the fourth carrier is any carrier among the one or more aggregated carriers, and the first information sent by the second terminal 102 on the fourth carrier is used to trigger SL IUC information of the first terminal 101. Exemplarily, the first information sent by the second terminal 102 to the first terminal 101 can be sent on any aggregated carrier to achieve the purpose of triggering the SL IUC report according to terminal granularity.

Exemplarily, the first information sent by the second terminal 102 on the fourth carrier may be the SL SCI or the SL IUC request MAC CE.

[0307] In some embodiments, the first information sent by the second terminal 102 on the fourth carrier may be included in the SL SCI and / or the SL IUC request MAC CE. Exemplarily, the first information sent by the second terminal 102 on the fourth carrier may be included in the SL SCI. For example, the second terminal 102 sends the SL SCI to the first terminal 101 on the fourth carrier, and the SL SCI includes the first information. Exemplarily, the first information sent by the second terminal 102 on the fourth carrier may be included in the SL IUC request MAC CE. For example, the second terminal 102 sends the SL IUC request MAC CE to the first terminal 101 on the fourth carrier, and the SL IUC request MAC CE includes the first information.

[0308] Step S2502 : The first terminal 101 sends an SL IUC MAC CE to the second terminal 102 .

[0313] In some embodiments, when the first terminal 101 determines that the SL IUC report is triggered by the first terminal 101 and the SL IUC report triggered by the first terminal 101 has not been canceled, the first terminal 101 starts the SL IUC timer associated with the first terminal 101; when the first terminal 101 determines that the SL IUC timer associated with the first terminal 101 has timed out, the first terminal 101 cancels the SL IUC report triggered by the first terminal 101. Exemplarily, when the SL IUC report of the first terminal 101 is triggered and the triggering status of the SL IUC report is not canceled (it can be understood that the first terminal 101 receives the first information from the second terminal 102 indicating that the SL IUC report of the first terminal 101 is triggered), if the SL IUC timer associated with the first terminal 101 is not running, the SL IUC timer associated with the first terminal 101 is started; if the SL IUC timer associated with the first terminal 101 times out, the SL IUC report triggered by the first terminal 101 is canceled.

[0314] In some embodiments, during the operation of the SL IUC timer associated with the first carrier, the first terminal 101 determines that the first terminal 101 has new transmission side link resources and the new transmission side link resources may include a SL IUC MAC CE and a sub-header of the SL IUC MAC CE; instructs the multiplexing and assembly entity to generate the SL IUC MAC CE; stops the SL IUC timer associated with the first terminal 101, and cancels the SL IUC report triggered by the first terminal 101.

[0315] That is to say, during the operation of the SL IUC timer associated with the first terminal 101, if the first terminal 101 has a new side link resource and the new side link resource may include a SL IUC MAC CE and a subheader of the SL IUC MAC CE, the multiplexing and assembly entity is instructed to generate the SL IUC MAC CE, stop the SL IUC timer associated with the first terminal 101, and cancel the SL IUC report triggered by the first terminal 101.

[0316] In some embodiments, the second terminal 102 sends the delay limit requirement of the SL IUC report to the first terminal 101 via PC5 radio resource control RRC signaling. Accordingly, the first terminal 101 receives the delay limit requirement of the SL IUC report sent by the second terminal 102 via PC5RRC signaling; wherein the duration of the SL IUC timer associated with the first terminal 101 is the delay limit requirement of the SL IUC report. Exemplarily, the delay limit requirement of the SL IUC report can be configured by the second terminal 102 to the first terminal 101 via PC5RRC signaling.

[0317] In some embodiments, the delay limit requirement of the SL IUC report associated with the first terminal 101 can be configured according to any of the following granularities: carrier granularity; frequency band granularity; frequency segment granularity; terminal granularity; target address granularity; address granularity. Exemplarily, the delay limit requirement of the SL IUC report can be configured according to terminal granularity, and the SL IUC timer associated with the first terminal 101 takes the size of the delay limit requirement of the SL IUC report associated with the first terminal 101.

[0318] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2E .

[0319] In the above embodiment, the second terminal sends the first information to the first terminal on any carrier. The first information is used to trigger the SL IUC information of the first terminal. The SL IUC report reported by the first terminal includes the SL IUC information of multiple carriers, which can achieve the purpose of triggering the SL IUC report according to the terminal granularity and the purpose of reporting the SL IUC report according to the carrier granularity, thereby solving the problem of how to trigger the SL IUC report in the new radio interface sidelink NR Sidelink carrier aggregation scenario.

[0320] Figure 2F is an interactive diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 2F, the information processing method according to an embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0321] Step S2601: The second terminal 102 sends first information to the first terminal 101 on the fourth carrier.

[0322] In some embodiments, the second terminal 102 sends first information to the first terminal 101, where the first information is sent by the second terminal 102 on the fourth carrier. Accordingly, the first terminal 101 receives the first information sent by the second terminal 102 on the fourth carrier.

[0323] In some embodiments, a unicast connection is established on the sidelink between the first terminal 101 and the second terminal 102, and the unicast connection is associated with one or more aggregated carriers.

[0324] The optional implementation of step S2601 can refer to the optional implementation of step S2501 in Figure 2F and other related parts in the embodiment involved in Figure 2F, which will not be repeated here.

[0325] Step S2602: The first terminal 101 selects a fifth carrier from the one or more aggregated carriers.

[0326] In some embodiments, the first terminal 101 may select any one carrier from the one or more aggregated carriers as the fifth carrier.

[0327] In some embodiments, the first terminal 101 may select a carrier with the lowest CBR (channel busy ratio) from the one or more aggregated carriers as the fifth carrier.

[0328] In some embodiments, the first terminal 101 may select a carrier with the highest CBR from the one or more aggregated carriers as the fifth carrier.

[0329] Step S2603 : The first terminal 101 sends an SL IUC MAC CE to the second terminal 102 .

[0330] In some embodiments, after the first terminal 101 selects a fifth carrier from the one or more aggregated carriers, the first terminal 101 may send a SL IUC MAC CE to the second terminal 102. Accordingly, the second terminal 101 may receive the SL IUC MAC CE sent by the first terminal 101. The SL IUC MAC CE includes the SL IUC of the fifth carrier and / or carrier indication information of the fifth carrier.

[0331] In some embodiments, the first terminal 101 may send an SL IUC MAC CE to the second terminal 102 on the fifth carrier, where the SL IUC MAC CE includes the SL IUC of the fifth carrier and / or carrier indication information of the fifth carrier. Correspondingly, the second terminal 101 may receive the SL IUC MAC CE sent by the first terminal 101 on the fifth carrier. The fifth carrier may be a carrier selected by the first terminal 101 from the one or more aggregated carriers.

[0332] In some embodiments, the SL IUC MAC CE sent by the first terminal 101 to the second terminal 102 may include the sidelink channel state information of the fifth carrier. Exemplarily, the first terminal 101 selects a fifth carrier from the one or more aggregated carriers, and sends the SL IUC MAC CE to the second terminal 102 on the fifth carrier. The SL IUC MAC CE may include the SLIUC information of the fifth carrier, and the SL IUC MAC CE may not carry the carrier indication information of the fifth carrier. For example, the first terminal 101 selects carrier A as the fifth carrier from the one or more aggregated carriers, and sends the SL IUC MAC CE to the second terminal 102 on the carrier A. The SL IUC MAC CE may include the SL IUC information of the carrier A, and the SL IUC MAC CE may not carry the carrier indication information of the carrier A.

[0333] In some embodiments, the SL CSI MAC CE sent by the first terminal 101 to the second terminal 102 may include the sidelink channel state information of the fifth carrier, and the SL IUC MAC CE may also include the carrier indication information of the fifth carrier. Exemplarily, the first terminal 101 selects a fifth carrier from the one or more aggregated carriers, and sends a SL IUC MAC CE to the second terminal 102 on a non-fifth carrier (such as other carriers other than the fifth carrier in the one or more aggregated carriers). The SL IUC MAC CE may include the SLIUC information of the fifth carrier, and the SL IUC MAC CE carries the carrier indication information of the fifth carrier. For example, the first terminal 101 selects carrier A as the fifth carrier from the one or more aggregated carriers, and sends a SL IUC MAC CE to the second terminal 102 on carrier B (such as carrier B is other carrier other than carrier A in the one or more aggregated carriers). Then, the SL IUC MAC CE may include the SL IUC information of carrier A, and the SL IUC MAC CE also needs to carry the carrier indication information of carrier A.

[0334] In some embodiments, when the first terminal 101 determines that the SL IUC report is triggered by the first terminal 101 and the SL IUC report triggered by the first terminal 101 has not been canceled, the first terminal 101 starts the SL IUC timer associated with the first terminal 101; when the first terminal 101 determines that the SL IUC timer associated with the first terminal 101 has timed out, the first terminal 101 cancels the SL IUC report triggered by the first terminal 101. Exemplarily, when the SL IUC report of the first terminal 101 is triggered and the triggering status of the SL IUC report is not canceled (it can be understood that the first terminal 101 receives the first information from the second terminal 102 indicating that the SL IUC report of the first terminal 101 is triggered), if the SL IUC timer associated with the first terminal 101 is not running, the SL IUC timer associated with the first terminal 101 is started; if the SL IUC timer associated with the first terminal 101 times out, the SL IUC report triggered by the first terminal 101 is canceled.

[0335] In some embodiments, during the operation of the SL IUC timer associated with the first carrier, the first terminal 101 determines that the first terminal 101 has new transmission side link resources and the new transmission side link resources may include a SL IUC MAC CE and a sub-header of the SL IUC MAC CE; instructs the multiplexing and assembly entity to generate the SL IUC MAC CE; stops the SL IUC timer associated with the first terminal 101, and cancels the SL IUC report triggered by the first terminal 101.

[0336] That is to say, during the operation of the SL IUC timer associated with the first terminal 101, if the first terminal 101 has a new side link resource and the new side link resource may include a SL IUC MAC CE and a subheader of the SL IUC MAC CE, the multiplexing and assembly entity is instructed to generate the SL IUC MAC CE, stop the SL IUC timer associated with the first terminal 101, and cancel the SL IUC report triggered by the first terminal 101.

[0337] In some embodiments, the second terminal 102 sends the delay bound requirement of the SL IUC report to the first terminal 101 via PC5RRC signaling. Accordingly, the first terminal 101 receives the delay bound requirement of the SL IUC report sent by the second terminal 102 via PC5RRC signaling; wherein the duration of the SL IUC timer associated with the first terminal 101 is the delay bound requirement of the SL IUC report. Exemplarily, the delay bound requirement of the SL IUC report can be configured by the second terminal 102 to the first terminal 101 via PC5RRC signaling.

[0338] In some embodiments, the delay limit requirement of the SL IUC report can be configured according to any of the following granularities: carrier granularity; frequency band granularity; frequency segment granularity; terminal granularity; target address granularity; address granularity. Exemplarily, the delay limit requirement of the SL IUC report can be configured according to terminal granularity, and the SL IUC timer associated with the first terminal 101 takes the value of the delay limit requirement of the SL IUC report associated with the first terminal 101.

[0339] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2F .

[0340] In the above embodiment, the second terminal sends the first information to the first terminal on any carrier, and the first information is used to trigger the SL IUC information of the first terminal. The first terminal selects the SL IUC information of one carrier from the aggregated multiple carriers for reporting, which can achieve the purpose of triggering the SL IUC report according to the terminal granularity, and can achieve the purpose of reporting the SL IUC report according to the terminal granularity, thereby solving the problem of how to trigger the SL IUC report in the new radio interface side link NR Sidelink carrier aggregation scenario.

[0341] Figure 2G is an interactive diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 2G, the information processing method according to an embodiment of the present disclosure can be applied to the communication system 100, and the method includes but is not limited to the following steps.

[0342] Step S2701: The first terminal 101 determines that the sixth carrier meets the triggering condition of the SL IUC information.

[0343] In some embodiments, a unicast connection is established on the sidelink between the first terminal 101 and the second terminal 102 , and the unicast connection is associated with one or more aggregated carriers.

[0344] In some embodiments, the sixth carrier may be one or more carriers among the one or more aggregated carriers. Exemplarily, the first carrier may be one or more carriers among the one or more aggregated carriers for which SL IUC reporting is triggered.

[0345] In some embodiments, the trigger condition that the sixth carrier meets the SL IUC information may be determined by the first terminal 101 based on the trigger condition of the SL IUC information. For example, the first terminal 101 determines that the sixth carrier meets the trigger condition of the SL IUC information based on the trigger condition of the SL IUC information. Alternatively, the trigger condition that the sixth carrier meets the SL IUC information may be indicated by the first terminal 101 based on other instructions. For example, the first terminal 101 receives a first instruction, and the first instruction indicates that the sixth carrier meets the trigger condition of the SL IUC information. This disclosure is not limited to this.

[0346] The triggering condition for sending the IUC information of the sixth carrier to the second terminal device may be a condition for sending the IUC information to the second terminal device in the related art, and the embodiment of the present disclosure does not impose any specific limitation on this.

[0347] Step S2702: The first terminal 101 sends an SL IUCMAC CE to the second terminal 102 on the sixth carrier.

[0348] That is to say, the sending of SL IUCMAC CE in this embodiment supports a condition-based triggering mechanism. In some embodiments, the first terminal 101 determines that the sixth carrier meets the triggering condition of the SL IUC information, and the first terminal 101 sends the SL IUCMAC CE to the second terminal 102; or, in response to the sixth carrier meeting the triggering condition of the SL IUC information, the first terminal 101 sends the SL IUCMAC CE to the second terminal 102. The SL IUCMAC CE is sent by the first terminal 101 on the sixth carrier. Accordingly, the second terminal 102 can receive the SL IUCMAC CE sent by the first terminal 101 on the sixth carrier. In some embodiments, the SL IUCMAC CE includes the SL IUC information of the sixth carrier.

[0349] Exemplarily, among the one or more aggregated carriers, carrier A and carrier B both meet the triggering conditions of the SL IUC information, then the first terminal 101 sends a SL IUCMAC CE to the second terminal 102 on carrier A, and sends a SL IUCMAC CE to the second terminal 102 on carrier B, wherein the SL IUCMAC CE sent by the first terminal 101 to the second terminal 102 on carrier A includes the SL IUC information (also referred to as IUC information) of carrier A, and the SL IUCMAC CE sent by the first terminal 101 to the second terminal 102 on carrier B includes the IUC information of carrier B.

[0350] That is, the first terminal 101 may only send the SL IUC report of the carrier on the carrier that meets the IUC trigger condition, and the SL IUC report may not carry the carrier indication information of the carrier. For example, the existing SL-IUC MAC CE format may be reused, and the reserved bit does not need to indicate the carrier information.

[0351] It should be noted that when the SLIUC report of the first carrier is triggered and the SLIUC report of the first carrier is reported, the influence of LCP can be taken into consideration, and the SL IUC MAC CE associated with the first carrier can only be sent on the sidelink grant (SL grant) on the first carrier. In some embodiments, the sidelink grant is determined to be a sidelink grant on the first carrier and / or the target address of the sidelink grant is the second terminal 102; the sidelink grant is a new transmission sidelink resource; the SL IUC MAC CE associated with the first carrier is multiplexed into a sidelink media access control protocol data unit (SL MAC PDU), and the SL MAC PDU is sent to the second terminal 102 through the sidelink grant.

[0352] For example, considering the impact of LCP, the SL IUC MAC CE of the first carrier can only be sent on the sidelink authorization on the first carrier. If the sidelink authorization of the LCP process is a sidelink authorization on other carriers, the SL IUC MAC CE of the first carrier is not considered in the LCP process.

[0353] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2G .

[0354] In the above embodiment, the SL IUC report based on conditional triggering can support triggering according to carrier granularity and support reporting according to carrier granularity.

[0355] Figure 2H is an interactive diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 2H, the information processing method according to the embodiment of the present disclosure can be applied to the communication system 100, and the method includes but is not limited to the following steps.

[0356] Step S2801: The first terminal 101 determines that the sixth carrier meets the triggering condition of the SL IUC information.

[0357] The optional implementation of step S2801 can refer to the optional implementation of step S2701 in Figure 2G and other related parts in the embodiment involved in Figure 2G, which will not be repeated here.

[0358] Step S2802: The first terminal 101 sends an SL IUCMAC CE to the second terminal 102 on the seventh carrier.

[0359] In some embodiments, a unicast connection is established on a sidelink between the first terminal 101 and the second terminal 102 , and the unicast connection is associated with one or more aggregated carriers.

[0360] In some embodiments, the seventh carrier may be one of the one or more aggregated carriers.

[0361] That is to say, the sending of SL IUCMAC CE in this embodiment supports a condition-based triggering mechanism. In some embodiments, the first terminal 101 determines that the sixth carrier meets the triggering condition of the SL IUC information, and the first terminal 101 sends the SL IUCMAC CE to the second terminal 102; or, in response to the sixth carrier meeting the triggering condition of the SL IUC information, the first terminal 101 sends the SL IUCMAC CE to the second terminal 102. The SL IUCMAC CE is sent by the first terminal 101 on the seventh carrier. Accordingly, the second terminal 102 can receive the SL IUCMAC CE sent by the first terminal 101 on the seventh carrier. In some embodiments, the SL IUCMAC CE includes the SL IUC information of the sixth carrier and / or the carrier indication information of the sixth carrier.

[0362] Exemplarily, if carrier A and carrier B among the one or more aggregated carriers mentioned above both meet the triggering conditions of the SL IUC information, the first terminal 101 sends a SL IUCMAC CE to the second terminal 102 on carrier C (such as other carriers except carrier A and carrier B among the one or more aggregated carriers mentioned above), wherein the SL IUCMAC CE sent by the first terminal 101 to the second terminal 102 on carrier C includes the SL IUC information of carrier A and the IUC information of carrier B, and the SL IUCMAC CE also includes carrier indication information of carrier A and carrier indication information of carrier B.

[0363] That is to say, the first terminal 101 can send the IUC information of the carrier that meets the IUC triggering condition on any other carrier. It is necessary to define a new SL-IUC MAC CE format and indicate the carrier information through reserved bits, such as the carrier index. Exemplarily, the new SL-IUC MAC CE can indicate the IUC information of one or more carriers. For example, if carrier A and carrier B trigger SL-IUC reporting respectively, the IUC information of carrier A and carrier B can be reported through the new SL-IUC MAC CE. For example, the SL IUC MAC CE can include the SL IUC information of carrier A and the IUC information of carrier B. The SL IUC MAC CE also includes the carrier indication information of carrier A and the carrier indication information of carrier B.

[0364] The triggering condition for sending the IUC information of the sixth carrier to the second terminal device may be a condition for sending the IUC information to the second terminal device in the related art, and the embodiment of the present disclosure does not impose any specific limitation on this.

[0365] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2H .

[0366] In the above embodiment, the SL IUC report based on conditional triggering can support triggering according to carrier granularity and support reporting according to carrier granularity.

[0367] Figure 2I is an interactive diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 2I, the information processing method according to the embodiment of the present disclosure can be applied to the communication system 100, and the method includes but is not limited to the following steps.

[0368] Step S2901: The first terminal 101 determines that the first terminal 101 meets the triggering condition of the SL IUC information.

[0369] In some embodiments, a unicast connection is established on the sidelink between the first terminal 101 and the second terminal 102 , and the unicast connection is associated with one or more aggregated carriers.

[0370] In some embodiments, the first terminal 101 may determine that the triggering condition for the SL IUC information is satisfied based on the triggering condition of the SL IUC information. For example, the first terminal 101 determines that the first terminal 101 satisfies the triggering condition of the SL IUC information based on the triggering condition of the SL IUC information. Alternatively, the first terminal 101 may be instructed by other instructions based on the triggering condition of the SL IUC information. For example, the first terminal 101 may receive a first instruction indicating that the first terminal 101 satisfies the triggering condition of the SL IUC information. This disclosure is not limited to this.

[0371] The triggering condition for sending the IUC information of the first terminal 101 to the second terminal device may be a condition for sending the IUC information to the second terminal device in the related art, and the embodiment of the present disclosure does not impose any specific limitation on this.

[0372] Step S2902 , the first terminal 101 sends SL IUCMAC CE to the second terminal 102 .

[0373] That is to say, the sending of the SL IUC MAC CE in this embodiment supports a condition-based triggering mechanism. In some embodiments, the first terminal 101 determines that the first terminal 101 meets the triggering condition of the SL IUC information, and the first terminal 101 sends the SL IUC MAC CE to the second terminal 102; or, in response to the first terminal 101 meeting the triggering condition of the SL IUC information, the first terminal 101 sends the SL IUC MAC CE to the second terminal 102. Accordingly, the second terminal 102 can receive the SL IUC MAC CE sent by the first terminal 101, and the SL IUC MAC CE can include SL IUC information of one or more aggregated carriers. Exemplarily, the SL IUC MAC CE sent by the first terminal 101 to the second terminal 102 includes the SL IUC information of all aggregated carriers. Exemplarily, the SL IUC MAC CE sent by the first terminal 101 to the second terminal 102 includes the SL IUC information of some aggregated carriers.

[0374] In some embodiments, the SL IUC MAC CE sent by the first terminal 101 to the second terminal 102 may also include carrier indication information of one or more aggregated carriers. The SL IUC MAC CE sent by the first terminal 101 to the second terminal 102 includes the SL IUC information of all aggregated carriers and the carrier indication information of all aggregated carriers. Exemplarily, the SL IUC MAC CE sent by the first terminal 101 to the second terminal 102 includes the SL IUC information of partially aggregated carriers and the carrier indication information of partially aggregated carriers. Exemplarily, the carrier information is indicated by reserved bits. Exemplarily, the reserved 3 bits can indicate up to 8 carrier information (e.g., carrier index). If 32 carriers are aggregated, the bits can be further extended to indicate the carrier information.

[0375] The triggering condition for sending the IUC information of the sixth carrier to the second terminal device may be a condition for sending the IUC information to the second terminal device in the related art, and the embodiment of the present disclosure does not impose any specific limitation on this.

[0376] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2I .

[0377] In the above embodiment, the SL IUC report based on conditional triggering can support triggering according to terminal granularity and support reporting according to carrier granularity.

[0378] Figure 2J is an interactive diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 2J, the information processing method according to the embodiment of the present disclosure can be applied to the communication system 100, and the method includes but is not limited to the following steps.

[0379] Step S2111: The first terminal 101 determines that the first terminal 101 meets the triggering condition of the SL IUC information.

[0380] The optional implementation of step S2111 can refer to the optional implementation of step S2901 in Figure 2I and other related parts in the embodiment involved in Figure 2I, which will not be repeated here.

[0381] Step S2112: The first terminal 101 selects an eighth carrier from one or more aggregated carriers.

[0382] In some embodiments, the first terminal 101 may select any one carrier from the one or more aggregated carriers as the eighth carrier.

[0383] In some embodiments, the first terminal 101 may select a carrier with the lowest CBR from the one or more aggregated carriers as the eighth carrier.

[0384] In some embodiments, the first terminal 101 may select a carrier with the highest CBR from the one or more aggregated carriers as the eighth carrier.

[0385] Step S2113 , the first terminal 101 sends SL IUCMAC CE to the second terminal 102 .

[0386] That is to say, the sending of SL IUCMAC CE in this embodiment supports a condition-based triggering mechanism. In some embodiments, the first terminal 101 determines that the first terminal 101 meets the triggering condition of the SL IUC information, and the first terminal 101 sends the SL IUCMAC CE to the second terminal 102; or, in response to the first terminal 101 meeting the triggering condition of the SL IUC information, the first terminal 101 sends the SL IUCMAC CE to the second terminal 102. Accordingly, the second terminal 102 can receive the SL IUCMAC CE sent by the first terminal 101, and the SL IUCMAC CE can include the SL IUC information of the eighth carrier and / or the carrier indication information of the eighth carrier. The eighth carrier can be a carrier selected by the first terminal 101 from the one or more aggregated carriers mentioned above.

[0387] In some embodiments, the SL IUC MAC CE received by the second terminal 102 may be the SL IUC MAC CE sent by the first terminal 101 on the eighth carrier (that is, the SL IUC MAC CE sent by the first terminal 101 to the second terminal 102 may be the SL IUC MAC CE sent by the first terminal 101 on the eighth carrier), then the SL IUC MAC CE includes the SL IUC of the eighth carrier, and the SL IUC MAC CE may not carry the carrier indication information of the eighth carrier. For example, if the first terminal 101 meets the triggering condition of the SL IUC information, the first terminal 101 selects carrier A as the eighth carrier from the one or more aggregated carriers mentioned above, and sends the SL IUC MAC CE to the second terminal 102 on the carrier A, then the SL IUC MAC CE may include the SL IUC information of the carrier A, and the SL IUC MAC CE may not carry the carrier indication information of the carrier A.

[0388] In some embodiments, the SL IUC MAC CE received by the second terminal may be sent by the first terminal 101 on a non-eighth carrier (that is, the SL IUC MAC CE sent by the first terminal 101 to the second terminal 102 may be sent by the first terminal 101 on a non-eighth carrier), then the SL IUC MAC CE also includes carrier indication information of the eighth carrier. Exemplarily, the first terminal 101 meets the triggering condition of the SL IUC information, the first terminal 101 selects an eighth carrier from the one or more aggregated carriers, and sends the SL IUC MAC CE to the second terminal 102 on a non-eighth carrier (such as other carriers other than the eighth carrier in the one or more aggregated carriers). The SL IUC MAC CE may include the SL IUC information of the eighth carrier, and the SL IUC MAC CE carries the carrier indication information of the eighth carrier. For example, the first terminal 101 meets the triggering condition of the SL IUC information, and the first terminal 101 selects carrier A as the eighth carrier from the one or more aggregated carriers mentioned above, and sends a SL IUC MAC CE to the second terminal 102 on carrier B (such as the carrier B is a carrier other than carrier A among the one or more aggregated carriers mentioned above). Then the SL IUC MAC CE can include the SL IUC information of the carrier A, and the SL IUC MAC CE also needs to carry the carrier indication information of the carrier A.

[0389] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2J .

[0390] In the above embodiment, the SL IUC report based on conditional triggering can support triggering according to terminal granularity and support reporting according to terminal granularity.

[0391] FIG3A is a flowchart of an information processing method according to an embodiment of the present disclosure. As shown in FIG3A , the present disclosure embodiment relates to an information processing method, which can be executed by the first terminal 101 and can include but is not limited to the following steps S3101 and S3102.

[0392] Step S3101: Receive first information sent by the second terminal 102 on a first carrier, where the first information is used to trigger the first terminal 101 to send SL IUC information of the first carrier.

[0393] In some embodiments, the first information may be sent by the second terminal 102 to the first terminal 101. Exemplarily, the second terminal 102 sends the first information to the first terminal 101 on the first carrier. Accordingly, the first terminal 101 receives the first information sent by the second terminal 102 on the first carrier, and the first information is used to trigger the first terminal 101 to send the SL IUC information of the first carrier.

[0568] In step S5101, the first terminal 101 sends an SL IUCMAC CE to the second terminal 102; a unicast connection is established on a sidelink between the first terminal 101 and the second terminal 102, and the unicast connection is associated with one or more aggregated carriers.

[0572] In some embodiments, the above method may include the method described in the above embodiments of the first terminal side, the second terminal side, etc., which will not be repeated here.

[0573] It should be noted that the present disclosure provides an IUC reporting method under SL carrier aggregation, which solves the problem of how to trigger the reporting of SL-IUC reports in the NR sidelink carrier aggregation scenario and how to maintain the timer.

[0574] In some embodiments, the SL-IUC report is triggered and reported at a carrier granularity, and the terminal (such as the first terminal 101 in this article) maintains a SL IUC timer (such as sl-IUC-ReportTimer) for each carrier associated with the unicast connection.

[0575] In some embodiments, the SCI and / or SL-IUC Request MAC CE that triggers the SL-IUC report sent by the peer terminal (such as the second terminal 102 in this document) is only sent on the carrier that is triggered to report. For example, if the peer terminal requests IUC information on carrier A, the SCI and / or SL-IUC Request MAC CE that triggers the SL-IUC report is only sent on carrier A. The SCI and / or SL-IUC Request MAC CE may not carry carrier information (the carrier information that triggers the IUC report). As another solution, the SCI and / or SL-IUC Request MAC CE that triggers the SL-IUC report sent by the peer terminal can be sent on any carrier, and the SCI and / or SL-IUC Request MAC CE carries carrier information (the carrier information that triggers the IUC report).

[0576] In some embodiments, the terminal (such as the first terminal 101) only sends the SL-IUC report of the carrier on the carrier that is triggered to report. Exemplarily, the existing SL-IUC MAC CE format is reused, and the reserved bit does not need to indicate the carrier information. As another solution, the terminal (such as the first terminal 101) can send the IUC information of the carrier that is triggered to report on any other carrier. It is necessary to define a new SL-IUC MAC CE format and indicate the carrier information, such as the index of the carrier, through the reserved bit. Exemplarily, the new SL-IUC MAC CE can indicate the IUC information of one or more carriers. For example, if carrier A and carrier B trigger SL-IUC reporting respectively, the IUC information of carrier A and carrier B can be reported through the new SL-IUC MAC CE.

[0577] In some embodiments, for each unicast connection associated with a source layer 2 address and a target layer 2 address pair established by a higher layer, the MAC entity of the terminal (such as the first terminal 101) starts the SL IUC timer associated with the first carrier and cancels the SL-IUC report triggered by the first carrier if the SL-IUC report is triggered and not canceled (the SCI and / or SL-IUC Request MAC CE of the opposite UE is received to indicate the triggering of the SL-IUC report of the first carrier). If the SL IUC timer associated with the first carrier is not running, the SL IUC timer associated with the first carrier is started. If the SL IUC timer associated with the first carrier times out, the SL-IUC report triggered by the first carrier is canceled. If there is a new sidelink resource and the LCP result is that the new sidelink resource can include the SL-IUC report and its subheader, the multiplexing and assembly entity is instructed to generate a SL-IUC MAC CE, the SL IUC timer associated with the first carrier is stopped, and the SL-IUC report triggered by the first carrier is canceled. Exemplarily, the duration of the SL IUC timer associated with the first carrier is the delay limit requirement of the SL IUC report associated with the first carrier (such as sl-LatencyBoundIUC-Report). Exemplarily, sl-LatencyBoundIUC-Report can be configured according to carrier granularity, and the SL IUC timer associated with the first carrier takes the size of the sl-LatencyBoundIUC-Report configured for the first carrier. Exemplarily, sl-LatencyBoundIUC-Report can be configured according to terminal granularity, and the SL IUC timer associated with the first carrier takes the size of the sl-LatencyBoundIUC-Report configured for the terminal.

[0578] In some embodiments, SL-IUC reporting is triggered at the terminal granularity and reported at the carrier granularity. The terminal maintains a SL IUC timer for the unicast connected carrier. The SL-IUC MAC CE indicates IUC information and carrier information of multiple carriers.

[0579] In some embodiments, the SCI and / or SL-IUC Request MAC CE that trigger the SL-IUC report sent by the opposite terminal (such as the second terminal 102) can be sent on any aggregated carrier. The MAC entity of the terminal (such as the first terminal 101) may, for each unicast connection associated with the source layer 2 address and the target layer 2 address pair established by the higher layer, start the SL IUC timer if the SL IUC timer is not running, and cancel the triggered SL-IUC report if the SL IUC timer expires. If there is a new sidelink resource and the LCP result is that the new sidelink resource may contain the SL-IUC report and its subheader, instruct the multiplexing and assembly entity to generate the SL-IUC MAC CE, stop the SL IUC timer, and cancel the triggered SL-IUC report.

[0580] In some embodiments, the SL-IUC report reported by a terminal (such as the first terminal 101) includes IUC information for multiple carriers. Exemplarily, the SL-IUC report reported by the terminal includes IUC information for all aggregated carriers. Carrier information is indicated by reserved bits. Exemplarily, the reserved 3 bits can indicate up to 8 carrier information, such as carrier indexes. If 32 carriers are aggregated, the bits can be further extended to indicate carrier information.

[0581] In some embodiments, the SL-IUC report is triggered and reported according to the terminal granularity, and the terminal device maintains an SL IUC timer for the unicast connection carrier.

[0582] Exemplarily, the SCI and / or SL-IUC Request MAC CE that trigger the SL-IUC report sent by the opposite terminal (such as the second terminal 102) can be sent on any aggregated carrier. The MAC entity of the terminal (such as the first terminal 101) generates a unicast connection associated with each source layer 2 address and target layer 2 address pair established by the higher layer. If the SL-IUC report is triggered and not canceled (the SCI and / or SL-IUC Request MAC CE of the opposite UE is received to indicate the triggering of the SL-IUC report), if the SL IUC timer is not running, start the SL IUC timer; if the SL IUC timer times out, cancel the triggered SL-IUC report; if there is a new sidelink resource and the LCP result is that the new sidelink resource can contain the SL-IUC report and its subheader, instruct the multiplexing and assembly entity to generate the SL-IUC MAC CE, stop the SL IUC timer, and cancel the triggered SL-IUC report.

[0583] Exemplarily, a terminal (such as the first terminal 101) selects the IUC of one carrier from the aggregated multiple carriers to report. It can select any aggregated carrier according to implementation, or select the carrier with the lowest / highest CBR, etc., and use the existing MAC CE format.

[0584] In some embodiments, the SL-IUC report based on conditional triggering is triggered according to carrier granularity and reported at carrier granularity.

[0585] Exemplarily, a terminal (such as the first terminal 101) only sends an SL-IUC report of the carrier that meets the IUC trigger condition. Exemplarily, the existing SL-IUC MAC CE format is reused, and the reserved bit does not need to indicate the carrier information. As another solution, the terminal can send the IUC information of the carrier that meets the IUC trigger condition on any other carrier. It is necessary to define a new SL-IUC MAC CE format and indicate the carrier information, such as the carrier index, through the reserved bit. Exemplarily, the new SL-IUC MAC CE can indicate the IUC information of one or more carriers. For example, if carrier A and carrier B trigger the SL-IUC report respectively, the IUC information of carrier A and carrier B can be reported through the new SL-IUC MAC CE. Carrier A can be an IUC report based on request triggering or an IUC report based on condition triggering, and carrier B can be an IUC report based on request triggering or an IUC report based on condition triggering.

[0586] In some embodiments, the SL-IUC report based on conditional triggering is triggered according to the terminal granularity and reported according to the carrier granularity.

[0587] Exemplarily, when the IUC trigger condition is met, the SL-IUC report reported by the terminal (such as the first terminal 101) includes IUC information of multiple carriers. Exemplarily, the SL-IUC report reported by the terminal includes IUC information of all aggregated carriers, and the carrier information is indicated by reserved bits. Exemplarily, the reserved 3 bits can indicate up to 8 carrier information, such as the carrier index. If 32 carriers are aggregated, the bits can be further extended to indicate the carrier information.

[0588] In some embodiments, the SL-IUC report based on conditional triggering is triggered and reported according to the terminal granularity.

[0589] Exemplarily, when the IUC triggering condition is met, the terminal (such as the first terminal 101) selects the IUC of one carrier from the aggregated multiple carriers to report. It can select any aggregated carrier according to the implementation, or select the carrier with the lowest / highest CBR, etc., and use the existing MAC CE format.

[0590] The embodiments of the present disclosure also provide apparatuses for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing each step performed by a first terminal in any of the above methods.
